This invention provides compounds useful for treating coronary insufficiency, hypertension, angina pectoris, cardiac arrythmia, heart attack or coronary vasospasm and represented by the general formula: ##STR1## R.sub.1 and R.sub.2 are each independently selected from the group consisting of lower alkyl, N-alkylphthalimido and derivatives of N-alkylphthalimido, wherein said N-alkyl group comprises at least 2 carbon atoms; A is a straight or branched chain hydrocarbon moiety containing from 1 to 12 carbon atoms and from 0 to 2 double bonds; R.sub.3 is selected from the group of radicals consisting of hydrogen, --NH.sub.2 and --NCS; R.sub.4 is an aryl or heteroaryl radical; and R.sub.5 is a lower alkyl radical or A--R.sub.3 ; provided that when R.sub.3 is a hydrogen radical at least one of R.sub.1 and R.sub.2 is not lower alkyl, including both pure enantiomers as well as mixtures thereof; and pharmaceutically-acceptable salts thereof.
这项发明提供了一种用于治疗冠状动脉血流不足、高血压、心绞痛、心律失常、心脏病发作或冠状动脉痉挛的化合物,其通式表示为:##STR1## 其中,R.sub.1和R.sub.2分别独立地选自由较低的烷基、N-烷基邻苯二甲酰亚胺及其衍生物的组,其中所述的N-烷基基团至少包含2个碳原子;A是含有1至12个碳原子和0至2个双键的直链或支链烃基;R.sub.3选自氢、--NH.sub.2和--NCS的基团组;R.sub.4是芳基或杂芳基基团;R.sub.5是较低的烷基基团或A--R.sub.3;但当R.sub.3是氢基团时,至少有一个R.sub.1和R.sub.2不是较低的烷基,包括纯对映体以及其混合物;以及其药用可接受盐。
